A cube of volume 1 m and specific gravity 2 is very slowly being lowered in to a lake with help of a massless string tied to one of its vertices as shown Initially the vertex B is just touching the surface of water and finally vertex A is just beneath the surface of water For the process of immersion match the columns Ignore change in KE of water g 10 ms Column 1 A Work done by gravity on water cube system B Work done by tension on the cube C Work done by gravity on water D Work done by gravity on the cube p 3 3 2 9 3 3 r 2 3 2 Column 11 x 104 Joule 10 Joule 10 Joule AT s 2 3x10 Joule t 40 3 10 Joule B
